This is a picture of the Cocoon Nebula, but it is cataloged as IC 5146. It is about 4,000 light-years away and can be found near the Swan constellation, Cygnus. Many new open clusters are developing in the Cocoon Nebula. Therefore, it also has a red emission nebula, blue reflection nebulas, and dark absorption nebulas. These nebulas produce the variety of colors that can be ssen in this photo taken by the CFHT in Hawaii. Recent measurements suggest that the large star on the left in this picture opened a hole in a molecular cloud; the glowing material flows through this hole.
